Combined Purchase. To receive a Class A or Class T front-end sales charge reduction, if you are a new shareholder, you may combine your purchase of Class A or Class T shares with purchases of: (i) Class A, Class T, Class B, and Class C shares of any Fidelity fund that offers Advisor classes of shares, (ii) Advisor B Class shares and Advisor C Class shares of Treasury Fund, and (iii) Class A Units (New and Old), Class B Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor 529 Plan. For your purchases to be aggregated for the purpose of qualifying for the Combined Purchase program, they must be made on the same day through one intermediary.

Rights of Accumulation. To receive a Class A or Class T front-end sales charge reduction, if you are an existing shareholder, you may add to your purchase of Class A or Class T shares the current value of your holdings in: (i) Class A, Class T, Class B, and Class C shares of any Fidelity fund that offers Advisor classes of shares, (ii) Advisor B Class shares and Advisor C Class shares of Treasury Fund, (iii) Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund acquired by exchange from any Fidelity fund that offers Advisor classes of shares, (iv) Class N and Class O shares of Destiny Portfolios I and II, and (v) Class A Units (New and Old), Class B Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor 529 Plan. The current value of your holdings is determined at the NAV at the close of business on the day prior to your purchase of Class A or Class T shares. The current value of your holdings will be added to your purchase of Class A or Class T shares for the purpose of qualifying for the Rights of Accumulation program. For your purchases and holdings to be aggregated for the purpose of qualifying for the Rights of Accumulation program, they must have been made through one intermediary.

Letter of Intent. You may receive a Class A or Class T front-end sales charge reduction on your purchases of Class A and Class T shares made during a 13-month period by signing a Letter of Intent (Letter). Each Class A or Class T purchase you make after you sign the Letter will be entitled to the reduced front-end sales charge applicable to the total investment indicated in the Letter. Purchases of the following may be aggregated for the purpose of completing your Letter: (i) Class A and Class T shares of any Fidelity fund that offers Advisor classes of shares (except those acquired by exchange from Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund that had been previously exchanged from a Fidelity fund that offers Advisor classes of shares), (ii) Class B and Class C shares of any Fidelity fund that offers Advisor classes of shares, (iii) Advisor B Class shares and Advisor C Class shares of Treasury Fund, and (iv) Class A Units (New and Old), Class B Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor 529 Plan. Reinvested income and capital gain distributions will not be considered purchases for the purpose of completing your Letter. You must file your Letter with Fidelity within 90 days of the start of your purchases toward completing your Letter. For your purchases to be aggregated for the purpose of completing your Letter, they must be made through one intermediary. Your initial purchase toward completing your Letter must be at least 5% of the total investment specified in your Letter. Class A and Class T shares acquired through an employee benefit plan, a Traditional IRA, a Roth IRA, a rollover IRA, a 403(b) program, or a plan covering a sole proprietor (formerly Keogh/H.R. 10 plan) will be included for purposes of completing your Letter but may not be used to meet the initial investment minimum of 5% of the total investment specified in your Letter. Fidelity will register Class A or Class T shares equal to 5% of the total investment specified in your Letter in your name and will hold those shares in escrow. You will earn income, dividends and capital gain distributions on escrowed Class A and Class T shares. The escrow will be released when you complete your Letter. You are not obligated to complete your Letter. If you do not complete your Letter, you must pay the increased front-end sales charges due. If you do not pay the increased front-end sales charges within 20 days after the date your Letter expires, Fidelity will redeem sufficient escrowed Class A or Class T shares to pay any applicable front-end sales charges. If you purchase more than the amount specified in your Letter and qualify for additional Class A or Class T front-end sales charge reductions, the front-end sales charge will be adjusted to reflect your total purchase at the end of 13 months and the surplus amount will be applied to your purchase of additional Class A or Class T shares at the then-current offering price applicable to the total investment.
